And ram. It's pretty hard to find anything that even hints at these with Google.

At this rate, I don't know. There's got to be some ram experts out there.

closest thing i could was this
http://i4memory.com/f50/drive-strength-settings-5380/

"the memory controller can adjust the drive strength according to overall system memory load. That is, with higher system memory density and consequently more memory chips that need to be driven by the controller, higher drive strength is necessary"

seems to be a setting that's used when running many chips of ram.

Yeah, I still don't really understand them. I'd like to know if they're tweakable, but I never screw with anything unless I understand it.

Everything is tweakable. smile.gif

Sometimes not knowing what you're doing while doing it is half the fun...

Just tweak and test, see if changing anything makes a difference. Tweak one thing at a time. It's time consuming, but perhaps the rewards may be very beneficial. thumb.gif
